Abstract
We have carried out Quantum Monte Carlo studies to investigate the double layer Hubbard model using the groundstate projector
formalism. Evidence for off diagonal long range order in the nodeless d-wave pairing channel is provided. It is emphasized
that the Projector Quantum Monte Carlo method has the potential to detect superconducting mechanisms in strongly correlated
electron systems, which are not treatable by standard analytic methods. The Monte Carlo technique provides useful information
about systems much larger than those accessible for exact diagonalization methods.
